Your XV144 should not get too hot, David.  I presume that yours will 
have vent holes in the top and bottom covers whereas the early ones 
(like mine) did not.  Now that I have provided ventilation I do not have 
a heat problem and can merrily run mine up to 25W. The Mitsubishi 
RA30H1317M PA module is in fact rated to have a Pout >30W at up to 
175MHz.
